Definitions

  • the invention relates to a method for transmitting data signals according to the preamble of claim 1.
  • Router will give the STM-256 / OC-768 signals with about 40 Gbit / s.
  • STM-256 / OC-768 signals with about 40 Gbit / s.
  • wavelength multiplex systems are still common at the moment, their individual channels for transmission rates of 10 Gbit / s are designed.
  • the object of the invention is to provide a method which the transmission of STM-256 / OC-768 signals over 10 Gbit / s channels allows.
  • pulse frames are used for transmission, which are essentially correspond to a standardized pulse frame. Only that The number of frame identifier bytes is reduced. Existing Transmission facilities therefore only need a minimal amount or not to be modified at all.
  • the pulse frame is like this designed that the operation of electrical regenerators is not affected. It can therefore be a unified Regenerator type can be provided in the network.
  • the original Signal is transmitted transparently.
  • FIG. 1 shows an application of the method according to the invention.
  • An STM-256 / OC-768 signal DSA is inserted into a pulse frame PR256 (FIG. 2) by a first router ROUT1 at a bit rate of approximately 40 Gbit / s.
  • this signal after the elimination of the bytes NU, A1, A2, NU byte-divided according to figure 2 in four cascaded partial signals IMA1 to IMA4 so that the bytes I11, I21, I31, I41, I12, I22, ... of the original 256 / OC-768 signal DSA are evenly allocated to the pulse frames PR64.1 to PR 64.4.
  • the exact structure of the pulse frame STM-64 / OC-192 is in the ITU Recommendation G.707, page 42 and pages 54 and 55.
  • the pulse frames PR64.1 to PR 64.4 used here correspond completely to those in format and content the STM-64 / OC-192 pulse frame, like this in the right half the figure 2 is shown. The representation is not to scale.
  • Each of these pulse frames has nine lines Z1 to Z9 and 17,280 columns S1, S2, ..., the so formed Time slots each take up one byte.
  • the ITU-like overhead the pulse frame PR64.1 to PR 64.4 each has 576 Columns on.
  • the "traditional overhead" comprises 576 columns.
  • the first useful signal byte 1537 of the STM-256 / OC-768 signal or the first byte of the partial signal IMA1 is in the first STM64 / OC-192 pulse frame PR64.1 inserted as byte I11 at position 377; the useful signal byte 1538 of the STM-256 / OC-768 signal at position 1538 or the first byte of the partial signal IMA2 is written as byte I21 at position 377 of the second STM64 / OC-192 pulse frame PR64.2 inserted etc. until the byte of position 1541 again as byte I12 at position 378 of the first pulse frame PR64.1 is inserted etc.
  • the concatenated signals IMA1 to IMA4 are combined and transmitted together with further signals in a first wavelength multiplexer WDM1 to form a transmission signal WS1.
  • the transmission path usually contains optical amplifiers OA1 and electrical regenerators RE1 to REn. For the regeneration, a division of the transmission signal by a first wavelength demultiplexer WDD1 into the corresponding 10 Gbit / s signals and then an opto-electrical conversion, not shown here, is necessary (still).
  • an electro-optical conversion takes place and the combination in a second wavelength multiplexer WDM2 to the transmission signal WS2, which is transmitted via a further optical amplifier OA2 to a second wavelength demultiplexer WDD2, where it is divided into sub-signals IME1 to IME4 is converted back, which correspond to the transmission-side partial signals IMA1 to IMA4.
  • Regenerator section overhead bytes J0, C, B1, E1, F1, D1, D2, D3 of the concatenated signals removed and the sub-signals are in the corresponding pulse frame PR256 "mapped" and again as STM-256 / OC-768 signal DSE fed to a second router ROUT2.
